Electric accumulators

Condensers. These are devices Used for a)con-centrating matter or energy b)cooling vapors to liquids cjpolymerization of org compds. Electrical condensers consist of insulared conductors which accumulate electricity. Optical condensers are instruments consisting of lenses or mirrors which condense light beams Ref Hackh s (1944), 220... 

The CCD array is composed of over 1.3 million detector elements that accumulate electrical charge in proportion to the intensity of the light on its surface and its exposure time. The operating software scans the detector array and determines which element contains the center of the beam. The software then maps all the other pixels according to their angular position. This eliminates the need for accurate optical alignment. 

Polyaniline filaments within the mesoporous channel host (aluminosilicate) have significant conductivity, and this demonstration of conjugated polymer with mobile charge carriers in nanometer channels represents a step toward the design of nanometer electronic devices. These composites have potential as stable molecular wires, which can be applied in the design of batteries and systems to accumulate electric charge. SBA-15 with polyaniline inside the pore channels was used as a dispersed phase in electro-rheological (ER) fluids. 

Contact with metals and some metal compounds may cause polymerization. Attacks most rubbers, plastics, and coatings. May accumulate electrical charges and cause ignition of its vapors. Thermal decomposition releases deadly hydrogen cyanide gas and nitrogen oxides. On small fires, use alcohol-resistant foam, dry chemical, or COj extinguishers. 

C TOOLS More about dielectrics and insulators An insulator is a material through which no steady conduction current can flow when it is submitted to an electric field. Consequently, an insulator can accumulate electric charge, hence electrostatic energy. The word dielectric, especially if it is used as adjective, covers a wide range of materials including electrolytes and even metals. 

The issue of accumulating electric energy produced by wind-power plants can be subject to either cen-trahsed or decentralised solutions respectively. The decisive factor here is the generating capacity of a wind farm, resp. its size or distribution ofwind-powerplants in case of individual installation layout. 

Many polymers exhibit good electric insulation properties and this makes them prone to accumulate electric charge. Static electricity is generated by the close contact of two materials of different composition, e.g., by rubbing. Dryness is an important factor for the generation of static electricity. Therefore, in winter time the problem of static electricity is still more pronounced.
